Final Answer:

1. The trigonometric ratios for
\( \cos(x) = -1/5 \)in the third quadrant are:


\( \sin(x) = -√(24)/5 \)


\( \tan(x) = √(24) \)


\( \tan(x) = √(24) \)
\( \tan(x) = √(24) \)


\( \sec(x) = -5 \)


\( \cot(x) = 1/√(24) \).

Step-by-step explanation:

Given that
\( \cos(x) = -1/5 \) and x is in the third quadrant, we can determine the other trigonometric ratios using the relationships between trigonometric functions. In the third quadrant,
\( \sin(x) \) is negative, and
\( \tan(x) \), \( \csc(x) \), \( \sec(x) \), and \( \cot(x) \)are positive.

Using the Pythagorean identity
\( \sin^2(x) + \cos^2(x) = 1 \), we find \( \sin(x) = -√(24)/5 \). The tangent
\( \tan(x) \) is calculated as
\( \tan(x) = \sin(x)/\cos(x) = -√(24) \).

The reciprocal functions are then obtained as
\( \csc(x) = 1/\sin(x) = -5/√(24) \), \( \sec(x) = 1/\cos(x) = -5 \), and \( \cot(x) = 1/\tan(x) = 1/√(24) \). Thus, the complete set of trigonometric ratios for
\( \cos(x) = -1/5 \) in the third quadrant is
\( \sin(x) = -√(24)/5 \), \( \tan(x) = √(24) \), \( \csc(x) = -5/√(24) \), \( \sec(x) = -5 \), and \( \cot(x) = 1/√(24) \).
